Case Study<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Background<\/h4>\n\n\n\n

In China, a leading manufacturer of TFT-LCD panels installed LG Chem\u2019s BW 400 ES L energy-saving reverse osmosis (RO) membrane elements for its ultrapure water (UPW) production process. The plant monitors increases in differential pressure (dP) for cues in membrane cleaning and TOC rejection as critical parameters for producing high-quality permeate.<\/p>\n\n\n\n

System Information<\/h4>\n\n\n\n
    \n
  • RO system design: 2 stage, 7:3 array (6M)<\/li>\n\n\n\n
  • No. of trains: 19<\/li>\n\n\n\n
  • RO system recovery: 89\u201390%<\/li>\n\n\n\n
  • Feed water temperature: 25\u201326\u00b0C<\/li>\n\n\n\n
  • pH: 7.5\u20138.5<\/li>\n<\/ul>\n\n\n\n

    Novel Feed Spacer<\/h4>\n\n\n\n

    LG BW 400 ES L incorporates a proprietary novel L feed spacer to reduce differential pressure. The result is a lower fouling rate and cleaning frequency, and overall operational cost savings. For more information on the L spacer,

    Membrane Performance<\/h4>\n\n\n\n

    At system start-up, the total differential pressure (1st and 2nd stages) of LG NanoH\u2082O\u2122 RO elements was about 20% less than the competitor\u2019s equivalent product, also equipped with a factory-supplied low dP feed spacer (Figure 1).
    Permeate production was similar for both elements at 80 m\u00b3\/hr with a 90% recovery rate. TOC rejection for NanoH\u2082O\u2122 membranes was measured between 78\u201380%, higher than the competitor model.<\/p>\n\n\n\n
